Li Meng's sudden words made me stunned for a moment.

I walked quickly to Li Meng's side and asked her, "What do you mean?" ”

Li Meng sneered, even though they were no longer visible, Li Meng's gaze still stayed in the corner where they had disappeared last.

"Their daughter died, they just shed a few tears, Ning Xiaobai is very likely not their biological child, but even if it is not biological, even if a friend dies, it will not be so calm." Li Meng said indignantly.

Li Meng is very angry now, she kept panting, and said angrily: "So it is very likely that they are patriarchal, and now that they have a second child, and it is a son, they start to ignore their daughter." ”

After listening to Li Meng's words, my heart was very complicated: "Tiger poison does not eat children, no matter how you say it, it is the meat that fell from your body, and it is also your own biological child, no matter how patriarchal it is, it shouldn't be like this......"

Li Meng snorted coldly, gritted his teeth and said, "If you don't like this child, why did you give birth to her in the first place?" She didn't beg to be your daughter! ”

Seeing Li Meng's huge reaction, I was a little dazed for a while, and I didn't open my mouth, and I didn't open my mouth. Even if this incident was what she guessed, it wouldn't have such a big reaction......

I took a deep breath and said to Li Meng: "We are policemen, not immortals, there are many things we can't manage, and we can't manage them." ”

Li Meng listened to me and agreed with me. She also took a deep breath and said angrily: "There are really all kinds of people in this world, all kinds of people are worthy of getting married and having children, and all kinds of people are worthy of being parents." ”

"Forget it, maybe things aren't what you guessed......" I pulled her arm and casually comforted her.

After a while, a child's cry came from the office building of the Ningzhou Public Security Bureau.

The sound was so harsh that it literally pierced through the sky, comparable to an air raid siren.

Immediately afterwards, the parents hugged the little boy who was crying bitterly and returned to the alarm hall on the first floor.

The parents' mood finally changed significantly, and they kept wiping their tears, grinning and crying silently.

Maybe a two-year-old boy doesn't know the difference between life and death, doesn't know why his sister is lying there, maybe his cry is just frightened.

But the irony is that the emotional changes of the two parents are not even as big as that of a two-year-old child.

But no matter what, this is not something we should take care of, we are police, we are criminal police, our duty is to investigate the truth of Ning Xiaobai's death, if it is he who kills, then we must solve the case and catch the murderer.

The next thing will be handed over to Lin Zifan, I pulled Li Meng back to the office of the serious crime team, I was really afraid that she would get angry and go to Ning Xiaobai's parents to theorize.

Obviously, we have more important things than theories.

The autopsy results have not yet come out, if Ning Xiaobai died by suicide, then we have to investigate the cause of Ning Xiaobai's death.

This time, we brought back a large amount of physical evidence from the crime scene, and we need to find the key clues we need from the details of these physical evidence.

Ning Xiaobai was strangled by the piano strings, so the clue should be related to the piano.

Jiang Tingbai was still busy in the trace examination department, and I took Li Meng and Jiang Tingbai to examine the physical evidence.

The focus of our review is the sheet music.

To be reasonable, none of the three of us know piano scores, and the various musical symbols on it are heavenly books to us, and the only thing we can understand is the title of the sheet music, as well as the lyrics of some popular music.

Soon, we found a somewhat strange clue in the score.

Among these scores, there are some brand new scores, and the paper is noticeably cleaner and very new. This is in stark contrast to the other scores, which all have a common name – "Black Sunday".

"Why do you print so many copies of the same song?" Li Meng asked a little puzzled.

We found a total of six scores called "Black Sunday" in the sheet music, because we couldn't understand the shop, we had to have the most primitive way - to find the difference.

We lay six sheet music flat on our desks and compare them line by line.

"This is a big tadpole, this is a two-tailed tadpole...... Next up is the inverted tadpole ......"

Forgive our ignorance, we can only give these notes a figurative name so that we can compare them......

The three of us lay on the desk and compared for ten minutes, our eyes were dazzled, and we couldn't compare the reason.

Because these six scores are not used to find differences for us, but to find the same.

There was no way, we just had to turn to the almighty network, and after typing "Black Sunday" in the search bar, we finally came up with the answer.

It turns out that these six scores of the same name are six versions that have been circulated among the people.

And that is the real original, no one knows.

Because as we investigate, there seems to be a horror story behind the piano score of "Black Sunday".

"Black Sunday" also has two strange names - "World Forbidden Song" and "Murder Music".

"Did you log on to a cult website?" Li Meng stood beside me, staring at my search interface, frowned suddenly, and asked in disgust.

"It's the same with you." I said lightly.

There are different rumors about the piano song "Black Sunday" on the Internet, but after all, they all express the same meaning, that is, many people who have heard this music have committed suicide mysteriously.

As police officers, we are naturally atheists and don't believe in such strange things at all.

Especially these rumors, these rumors have been subjectively told by people, and when the rumors are told to others, they are already another version. Therefore, almost all rumors have become unrecognizable because of false rumors, and even run counter to the facts.

I've also heard a lot of rumors about this being labeled as another label, such as the songs "Sister Carries a Doll", "Wedding Dress", "Sunny Day Doll", and the 93 Guangzhou-Kowloon Railway advertisement, etc., and the final truth is that it makes people laugh off their big teeth.

But this song, coupled with this case, made me not laugh at all.

Because Ning Xiaobai has six copies of the score of "Black Sunday" at home, and Ning Xiaobai was strangled to death by piano strings, suspected of suicide. And it's Sunday......

Thinking of this, none of us spoke again, because we were all aware of the strangeness in it.

Although none of us said anything about the relationship between the two, our hearts were no longer firm......
